BRADFORD s. MILES, OF GRAYS SUMMIT, nissotfiif.

STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 227,914, dated May 25,1880;

' Application filed December 18, 18 79.

To all whom it may concern:

Be it known that I, BRADFORD S. Moms, of Grays Summit, in the county ofFranklin and State of Missouri, have invented certain new and usefulImprovements in Stump-Pullers; and I do hereby declare the following tobe a full, clear, and exact description of the intention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain improvements in stump-extractors; andit has for its object to pro ide a portable machine that may be readilyconveyed from place to place, and in which the parts, while beingoperated in one 'directionto extract the stump, will be automaticall yarranged to be operated in a reverse direction for a succeedingoperation, whereby the delay necessary in bringing the parts to a normalposition to begin operations, common to the ordinary stump-extractors,is obviated, and also for varying the power, and consequently the speed,of the parts, whereby the stump may be started at the beginning of theoperation, and quickly withdrawn toward the end of the operation, whenproperly loosened.

To this end theinvention consists in a powerful frame, constructed ofwood'or iron and mounted on wheels, for facilitating transportation, thesaid frame having at each end a vertical capstan, the forward capstan,at its lower end, carrying the guide-wheels of the apparatus. Said frameis also provided with a horizontal Windlass mounted upon a suitableshaft journaled in bearings in the frame, the forward end of said shaftbeing provided with a large pulley or wheel, which is connected with thecapstans, respectively, by means of chains secured to the periphery ofsaid pulley or wheel in parallel grooves, and passing around the same inopposite direct-ions, whereby the pulley or wheel may be rotated ineither direction by operating one or the other of the capstans.

The Windlass is provided with suitable lifting-chains depending fromopposite sides of the same, the said lifting-chains, as well as thecapstan, being arranged in such manner that as one is unwound the otherwill be wound,

so as to automatically arrange the parts at each operation for the nextsucceeding operation. The capstans and the Windlass are each providedwith a movable drum having angular recesses at one or both edges,'thesaid drums being capable of being shifted so as to engage the chains andincrease the circumference of the winding-surfaces for accelerating the,operation of the apparatus, as more fully hereinafter specified.

In the drawings, Figure 1 represents a side elevation of my improvedstump-extractor, and Fig. 2 a top view of the apparatus.

' The letter A indicates the frame of the apparatus, which may beconstructed of heavy timber, iron, or other material of requisitestrength. The said frame has mounted in suitable bearings at the frontand rear ends the vertical capstans B. The base-rails a of the frame Aare journaled in suitable bearings, the shafts 11 carrying the wheels 0,upon which. the main weight of the apparatus is supported. The lower endof the forward capstan is provided with wheels D, which form theguidewhecls of the apparatus in transporting the same from place toplace. Each capstan is provided with the levers E, which have hitchingattachments e at their ends, by means of which horses or otherdraft-animals may be attached for operating the capstans, the lovers ofthe forward capstan also serving as a means by which the animals may besecured to the apparatus for drawing it from place to place.

The letter F indicates a Windlass mounted on a horizontal shaft, G,which is journaled in suitable bearings, H, at the upper part of theframe A. Said shaft, at its forward end, is provided with alarge pulleyor wheel,I, which is provided with two parallel grooves, 17, on itsperiphery, in which are secured at one end the chains K, which arepassed in oppositedirections around the wheel or pulley, one beingattached to each capstan.

The capstans are each provided with a movable drum, L, having angularnotchesl at its lower end, said drums being held in a normal positionbythe pins 'M, and capable of being dropped by the removal of said pins,so as to engage the chains and wind the same thereon when it isdesiredto accelerate the motion of the pulley and Windlass. The Windlassis provided with a similar drum, N, having similar inclined recesses nat both edges, in order that it may engage either of the lifting-chainsO for a similar purpose.

The chains 0 are attached at one end to the windlass, and are passed inopposite directions over the same, and are provided with weights to keepthem taut, so that as one is wound upon the windlass in exerting astrain upon a stump the other is unwound, so as to be ready for asucceeding operation, the proper chain being secured to the stump by anyordinary or convenient means.

The operation of my invention will be apparent from the abovedescription. The apparatus is hauled over the stump, so as to bring thewindlass into proper position. The unwound chain of the windlass is thensecured to the stump, and power is applied to the capstan from which thechain is unwound. Upon rotating said capstan the chain attached to thesame will be wound thereon, rotating the pul-- ley and windlass andstarting the stump. When the stump is properly started the drums on thecapstan and windlass are thrown into operation, so as to seize and carrytheir respective chains, whereby the stump is quickly removed. Duringthe operation of the abovementioned capstan the other capstan isunwound, and the wound chain on the windlass is unwound, thus puttingthe parts in position for a succeeding operation.

Having thus fully described my invention, what 1 claim, and desire tosecure by Letters Patent, is-

1. The combination, in a stump-extractor,

of a frame provided with two capstans, connected by means of suitablechains to a pulley mounted on a shaft carrying a windlass havingoppositely-wound lifting-chains, whereby said windlass may be operatedalternately in opposite directions, substantially as and for thepurposes specified.

2. The combination, in a stump-extractor, of the supporting and guidewheels, the capstans ,and pulley mounted on the windlassshaft, thewindlass and its oppositely-wound lifting-chains, and the drums on thecapstans and windlass, the whole arranged to operate substantially inthe manner specified.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of November, 1879.
